ELECTRIC-LIGHT DEVICE.

Application ined` January ai,y 1922. semaine. 530,890.

This invention relates toelectric'lamp` sockets, the primary objectv of the invention beingto provide a socket embodying a novel switch mechanism, whereby the electric current through the lamp supported within the socket may be eiiiciently controlled.

Another object of the invention is to provide a switch mechanism which is eX- ceptionally simple in operation, and one which embodies few parts, eliminating the use of spring control. contact members for completing the circuit toI the lamp.

With the foregoing and other objects in View which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise. embodiment of the invention herein disclosed, may be made within the scope of what is claimed, without departing from the spirit of the invention.

Referring to the drawing Figure 1 is a side elevational View of a lamp socket constructed in accordance with the present invention.

Figure 2 is a vertical sectional View". through the lamp socket.

Figure 3 is a sectional view taken on line 3 3 of Figure 1.

Figure 4 is an end elevational view of the socket.

Referring to the drawing in detail, the socket comprises a base 5 formed of suitable insulating material such as porcelain or the like, the same being formed with an extension 6 which has external lthreads to accommodate the shell 7, whereby the socket may be screwed intothe usual lamp socket.

Extending through the body portion 5 is a rod 8 that carries a contact member 9 at one end thereof, the contact member 9 being provided to engage the usual central contact member of a lamp socket, to complete the circuit through the rod 8. A contact member 10 is formed on the opposite end of the rod 8, the'contact member 10 being of the spring type to engage' the `usual contact member of 'an electric lamp.

l Secured to the body portion 5 is a tubuf lar housing 11 formed with an, opening 12 to accommodate the rflexible operating mem- 'ber 13`vvhich is in the form of ajcord or Vchain positioned 'around the socket member 14 'and secured (thereto at avpoint intermediate its lengthl asv at 14, s'o thatapull on the member 13 will result in a relative movement of the socket member 14. The socket member 14 is mounted within the tubular housing 11 to movein a horizontal plane, the rod 8 acting as a pivot for the socket member 14 as clearly shown by Figure 2 of the drawing.

Forming a part of the socket member 14 is an end wall 15 through which the rod 8 extends, suitable insulating'LA disks 16 vand 17 being positioned on opposite sides of the end wall 15 to insulate the rod from the socket member 14.

The end Wall 15 is formed with a cut out portion 18 providing a clearance for the contact member 19 that has connection with the shell 7 and extends through a suitable opening formedin the body portion 5. As shown the inner end of the contact member 19 lies within the path of travel of the finger 20, which forms a part of the end wall 15, the finger 20 being formed of resilient material to permit it to move into close engage ment with the member 19 and complete the circuit through the socket'member to the bulb positioned ywithin the socket member 14.

In the use `of the device, assuming that an electric lamp is positioned-in the socket member 14, and one of the exible operat.

ing members 13 is pulled to bring the head 21 of the nger 20 into contact with the contact membery 19. It follows that the circuit is completed to the lamp positioned in' the socket member 14 to the end that kthe the circuit to the lamp, it is only necessary -ArENfFr to pull the opposite operating member 13 y to disengage the head 21 and contact mem-z ber 19.

Having thus described the invention, what is claimed as'new is :-Y n

,1. A lamp socket including a body portion, a tubular housing supportedby the body portion, a 90pm@ member extending through the body portion and terminating Within the housing, a rotatable socket member carrying a finger supported Within the tubular housing, a contact member eXtending through the body portion and being disposed substantially centrally of the socket member, and means for rotating the socket member to bring the finger into engagement With the first mentioned contact member to complete a circuit through a lamp supported Within a socket member.

2. A lamp sockeit including a body portion, a housing carried by the body portion, a socket member Within the housing, means for rotating the socket member, contact members extending through the body portion, a contact member carried by the socket member, and said contact member Acarried by the socket member adapted to complete a circuit through one of `the contact members when the socket member is rotated.

3. A lamp socket including a body portion, a housing secured to the body portion, a socket member supported Within the housing and including an end Wall, said end wall having a cut out portion, a contact member extending through the body portion and lying Within the cut out portion of the end Wall, a finger' carried by the socket member and adapted to engage'the contact member to complete a circuit, and means for rotating the socket member.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two Witnesses.
